Have a 99 F250 with a manual tranny. My clutch doesn't slip at all, but must be pushed all the way to the floor to be fully disengaged and grabs instantly off the floor. Tons of play up top. Definitely not normal. Any ideas what is causing this?

I recently bought the truck, but have driven it for the last 4/5 years at work. Been like that for a long time.

with the slop your describing, i'd suspect the fluid in the master/slave assy in done. Can order a complete kit from Advanced Auto, which is an all aluminum construction, for 130 buks, or go to ur local napa/oreilly's and get one, which are plastic..(same as the oem one).

Also, possible the clutchfork is bent. You can remove the slave assy from the tranny, and measure it. Should be, i think 2.5-2.75in gap, from fork to outside housing of tranny.

I've also got this problem with the ZF6 behind my 6.0, except sometimes if I get the motor up into the higher rpm's then the clutch pedal will stick to the floor and I'll have to pull it back up. I'm assuming that the ZF6 trans for the 6.0 and 7.3 are similar, if not the same.
